(Sept. 2011) A Battery Design Fault Leads to a Recall by Medtronic

 A Class I recall by the FDA   on Medtronic’s SynchroMed ll (an implantable pump which delivers drugs) was announced on September 12, 2011. A malfunction caused by a film formation on the pump’s  battery caused the pump to stop therapy.  Such problems were not noted until 45 to 78 months after the pumps had been implanted.  

 Models  8637-20 and 8637-40 could  be defective because of the batteries.  Physicians have been alerted. 

  Medtronic received FDA approval for a new battery design in July for the pumps.   Shipment of new units has already begun.
